Chris Pratt and Katherine Schwarzenegger are officially engaged, you guys! The Parks & Recreation star announced the happy news on his Instagram by sharing a really cute selfie from the moment his fiancée said yes. And lemme just tell you, the whole thing is incredibly romantic. "Sweet Katherine, so happy you said yes!" Pratt wrote in the post's caption. "I'm thrilled to be marrying you. Proud to live boldly in faith with you. Here we go!" Awwwww! And if you're wondering what the actor's ex-wife had to say about Pratt moving on, you'll be happy to know that Anna Faris' reaction to Chris Pratt and Katherine Schwarzenegger's engagement is actually so sweet!

"I'm so happy for you both!!" she wrote in the comment section of the post. "Congratulations!"

Lots of exclamation points there, so it looks like it's all love between the exes, you guys! I mean, the Mom actress is obviously excited about Pratt's big announcement, and her well wishes bode really well for the former couple — who separated in July 2017 after eight years of marriage — and their commitment to raising their son Jack together.

Anyway, here's the picture of the sweet proposal moment that the Guardians of the Galaxy star shared on Instagram early in the morning of Monday, Jan. 14:

"She knows Chris through mutual friends," the source said at the time.

I don't know if that rumor is actually true or not, but what I do know is that Shriver left a pretty amazing and supportive comment on Pratt's engagement post, too: "Congratulations to two loving, kind, caring, thoughtful, Spiritual people," she wrote. "We are so happy for you. You are blessed, as is everyone who knows you. Yes, let's go."
